IMPROVEMENT IN PUMPS.

To all whom t may concern:

Be it known that I, L. A. GOULD, of Santa Clara, in the county of SantaClara and State ot' California, have invented a new and usefulImprovement in Pumps; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming part ot' this specification.

The nat ure of this imi'n'ovement consists in arranging within thebarrel ot' the pump two pistons or buckets and operating the same insuch a manner through devices connecting them with the handle orbrake-lever of the pump that as one'bucket ascends the other descends,and vice versa, whereby a perpetual iiow of liquid through the pump isobtained and without the use of an air-chamber.

The figure in the accompanying plate of drawings illustrates myimprovement, it being a central vertical section through the barrel of'the pump and its buckets or pistons, showing` the connecting parts andoperating devices in side elevation.

lone above and a short distance from the other, each of which isprovided with a valve, g, made ot' metal or any other suitable material5 h, thc piston-rod of the lower bucket, secured at its lower endthereto in any proper manner, and passing upward inlthe central verticalaxis ofthe pump-barrel to and through the vertical hollow sleeve orshaft l of the upper bucket, f', the upper end of which sleeve Z is hungby pins m m upon its outside to the slotted end u of the short arm 0 ofthe lever or brake handle p, turning upon a fulcrum, g, between thestandards r of the top of the pumpbarrel.

i On the upper side of the brake arm or lever p, at or near its fulcrum,is a sector-shaped gear, s, interlocking with a similar sector-gear, t,above the same, and turning in bearings ot' the said standards r, to theouter end of the projecting arm u of which gear t the upper end of thepiston-rod h of the lower bucket is h ung, as plainly'shown in thedrawing by partially breaking` out the rod.

Around the periphery of each bucket are a series of parallel grooves, ofu, which may consist of two or more, and be made of a square, round, orany other suitable shape in which any packing, whether made of leatheror other material ordinarily used, is placed for causing the buckets towork with suflicient tightness in the pump-barrel to prevent any leakageabout them.

By the manner in which the two buckets of the pump are arranged withregard to and connected with each other through a common operatinghandle-lever, as above described, it is obvious that as one bucketdescends the other ascends, and vice versa, and that therefore acontinuous discharge of liquid through the nozzle of the pump isproduced, and without using an air-chamber within the pump, theadvantages ot` which are manifest to all conversant with pumps forraising liquids, Snc.

I claim as new and desire to secure by Letters Patent- Connecting therod h and hollow sleeve l, respectively, ot' two buckets, f and f', ot'a pump to a common actuating lever handle or brake, on which the rod Lis hung through the sector-shaped gears s and t and arm u, all arrangedand operating as and for the purpose specified.

rIhe above specification of my invention signed by me this 6th day ofJune, 1865.
